2 Overview he QS30AF is an easy-to-use triangulation sensor which provides a sophisticated, yet cost-effective solution for demanding applications. Yellow Output Conducting Indicator Green Power ON Indicator Configuration Push Buttons he sensor features two identically configured outputs, one each NPN and PNP. he sensor s compact housing has a large, easy-to-see bargraph display plus bright LEDs for easy configuration and status monitoring during operation. he sensor can be side-mounted, using its integral mounting holes, or front-mounted, via its 30 mm threaded barrel. Optical riangulation he function of the QS30AF Sensor is based on optical triangulation (see Figure 2). he emitter circuitry and optics create a light source which is directed toward a target. he light source bounces off the target, scattering some of its light through the sensor s receiver lens to its position-sensitive-device (PSD) receiver element. he target s distance from the receiver determines the light s angle to the receiver element; this angle determines where the returned light falls on the PSD receiver element. Bargraph Display Switchpoint SEUP Status Indicators: Delay Normally Closed Normally Open Figure 1. QS30 features he position of the light on the PSD receiver element is processed through digital electronics and analyzed by the microprocessor. he microprocessor will compare the target position to the cutoff limits and then change the outputs as required.

3 Sensor Configuration he sensor s cutoff point is set using a simple procedure, via either the push buttons or the remote wire. hree methods are available: Background Suppression SE, Object Detection SE, and Dynamic SE (remote only). After the sensor has been set for the target application, manual adjustments (via the + and push buttons) may be used to fine-tune the cutoff point. Sensor output configuration (N.O./N.C.) and the OFF-delay function are also set via the push buttons. Sensing Distance (D) Remote Configuration he Remote Configuration function may be used to configure the sensor remotely or to disable the push buttons for security. Connect the gray wire of the sensor to ground (0V dc), with a remote switch connected between them. Pulse the remote line according to the diagrams in the configuration procedures. he length of the individual pulses is equal to the value : 0.04 seconds 0.8 seconds Minimum Range Objects in this area are sensed Approx. 5% of Sensing Distance Figure 3. Background Suppression SE Push Button Background Background Suppression SE he distance to the background is sampled; the sensor places the cutoff point at approximately 95 percent of the distance to the background. In RUN mode, objects located between the minimum range and the taught cutoff are sensed; anything beyond the cutoff (e.g., other objects or background surfaces) is ignored. Minimum range varies, depending on the cutoff distance and reflectivity (see Figure 11). Remote 0.04 seconds 0.8 seconds Result Set Background Present background condition. Press and hold Background (+) push button > 2 seconds (until indicators flash). Present background condition. Single-pulse the remote line. Indicator segments 7 and 8 alternately flash. NO NC Return to RUN Mode Sampling continues until the push button is released; then sensor returns automatically to RUN mode. Sensor returns to RUN mode. If cutoff is accepted, sensor returns directly to RUN mode. If cutoff is beyond sensor range, Feedback is displayed for 2 seconds (see page 6).* * Segments 7 and 8 simultaneously flashing: Indiscernible target; sensor defaults to maximum cutoff. Segments 1 and 2 simultaneously flashing: Background is nearer than minimum cutoff; sensor defaults to minimum cutoff.

4 Object Detection SE Sensing Distance (D) he distance to the target is sampled; the sensor places the cutoff point at approximately 105 percent of the distance to the target. In RUN mode, objects located between the minimum range and the cutoff are sensed; anything beyond the cutoff (e.g., other objects or background surfaces) is ignored. Minimum range varies, depending on the cutoff distance and reflectivity (see Figure 11). Objects in this area are sensed Minimum Range Figure 4. Object Detection SE arget Object Approx. 5% of Sensing Distance Push Button Remote 0.04 seconds 0.8 seconds Result Sample arget Object Present target object. Press and hold Object (-) push button > 2 seconds (until indicators flash). Present target object. Double-pulse the remote line. Indicator segments 5 and 6 alternately flash. NO NC Return to RUN Mode Sampling continues until the push button is released; then sensor returns automatically to RUN mode. Sensor returns automatically to RUN mode. accepted: Sensor returns directly to RUN mode. beyond sensor range: Feedback is displayed for 2 seconds (see page 6).* * Segments 7 and 8 simultaneously flashing: Indiscernible target; sensor defaults to maximum cutoff. Segments 1 and 2 simultaneously flashing: set is nearer than minimum cutoff; sensor defaults to minimum cutoff. Manual Adjust Click the push buttons ( + or - ) to adjust the cutoff by approximately 2 percent. - o suppress background more, click Background button. - o increase object detection, click Object button. he display will momentarily blink to acknowledge cutoff movement. If the cutoff is at an extreme, the far (7th and 8th) or near (1st and 2nd) bargraph segments will flash simultaneously to indicate that the cutoff did not adjust.

5 Sensing Distance (D) Dynamic SE Objects in this area are sensed Minimum Range Figure 5. Dynamic SE arget Object Push Button Background Sensor places cutoff switchpoint midway he sensor samples the distances to both the target objects and the background surface; the sensor places the cutoff point midway between the object and the background. In RUN mode, objects located between the minimum range and the cutoff are sensed; anything beyond the cutoff (e.g., other objects or background surfaces) is ignored. Minimum range varies, depending on the cutoff distance and reflectivity (see Figure 11). Remote 0.04 seconds 0.8 seconds Result Sample arget Present and Absent Conditions Not available via push button Hold remote line low > 2 seconds (until indicators flash); continue to hold low while presenting at least 1 full application cycle > 2 seconds Indicator segments 1 and 8 alternately flash. NO NC Return to RUN Mode Sampling continues until the remote line is released; then sensor returns automatically to RUN mode. accepted: Sensor returns directly to RUN mode. beyond sensor range: Feedback is displayed for 2 seconds (see page 6).* * Segments 7 and 8 simultaneously flashing: Indiscernible target; sensor defaults to maximum cutoff. Segments 1 and 2 simultaneously flashing: set is nearer than minimum cutoff; sensor defaults to minimum cutoff.

6 Bar Graph Indicator Functions RUN Mode Lighted bargraph segment represents relative distance from the cutoff point. All segments OFF: No object is detected within the visible range. SE Mode Segments 7 and 8 alternately flashing: Background Suppression SE is active Segments 5 and 6 alternately flashing: Object Detection SE is active Segments 1 and 8 alternately flashing: Dynamic SE is active SE Mode Feedback If the cutoff point is accepted, the sensor returns immediately to RUN mode. If the taught cutoff point is beyond sensor range (closer than 50 mm or farther than 300 mm), the following are indicated for 2 seconds. (he sensor defaults to either maximum or minimum cutoff, then returns to RUN mode.) Segments 7 and 8 simultaneously flashing: Indiscernible target; either no target or a highly reflective target (see page 7). Sensor defaults to maximum cutoff. Segments 1 and 2 simultaneously flashing: arget is nearer than minimum cutoff. Sensor defaults to minimum cutoff. SEUP Mode SEUP mode (accessible via push buttons only) is used to change sensor output response for: Normally Closed or Normally Open operation 30-millisecond pulse stretcher (OFF-delay), if required he status LEDs, active only during SEUP mode, indicate the output response configuration when the sensor will be in RUN mode. Four combinations are possible: Normally Open, No Delay Normally Closed, No Delay Normally Open, 30 ms Delay Normally Closed, 30 ms Delay o access SEUP mode and change the output response settings: 1) Press and hold BOH push buttons simultaneously until the green LED indicator turns OFF. 2) Click EIHER push button to toggle through the four possible setting combinations. 3) Sensor returns to RUN mode after push buttons are inactive for 4 seconds. NOE: Outputs are active during SEUP mode. SEUP { Status Indicators Figure 6. SEUP mode Press and hold both push buttons to access SEUP mode Push Button Disable In addition to its configuration function, the remote wire may be used to disable the push buttons for security. Disabling the push buttons prevents accidental or unauthorized adjustment of the sensor settings. Connect the gray wire of the sensor as described on page 3, and four-pulse to either enable or disable the push buttons:

7 Installation Notes Sensor Orientation Some targets (those with a stepped plane facing the sensor, a boundary line, or rounded targets) pose specific problems for sensing distances. For such applications, see Figure 7 for suggested mounting orientation. Cookies Recommended Orientation Orientation Not Recommended Core of Emitted Beam Sensing Field Strong Direct Reflection to Near End of Detector Distance Reflective Background Figure 8. Reflective background problem Figure 7. Sensor orientations for typical targets Highly Reflective Backgrounds Use caution when sensing mirror-like background surfaces that produce specular reflections. False sensor response can occur if a background reflects the sensor s light more strongly to the near end of the detector than to its far end, resulting in a possible false ON condition. Use of a diffusely reflective (matte) background will cure this problem. Other possible solutions are to angle either the sensor or the background (in any plane) so that the background does not reflect back to the sensor (see Figures 8 and 9). For these applications, the Object Detection SE procedure is recommended. Sensing Field Distance Reflective Background Core of Emitted Beam Strong Direct Reflection Away From Sensor Figure 9.
